EXAMPLE FOR MOUSE MODE:
-Click on "Reload Mouse mode"
-Scroll down and click on "Map"
-Click the "Change to TAB" Button
-Scroll down to "Normal/Attack"
-Click the "change to..." Button and press "E"
-Save it!
-Now you can open your Map with "Tab" and attack with "E"

look at this guy.. making things all nifty and compatible for everyone. way to go man, im playing with it now. this should be pinned.

let me ask though, since the majority of ToS is played through keyboard (or game controller), wouldn't we want to be on the "Keyboard Mode" tab instead?

EDIT: It works perfectly! i set it up exactly like ragnarok. alt & numbers to use the emote-stances, alt & e for invent alt & q for status alt & z for party list ect ect. This patch is legit. It even helped me personally because my computer is backwards. i have to use FN & F key just to get the actual F1/F2/ect command (which makes it a pain in the arse because i was having to use 2 buttons to sit down instead of one). thanks so much for this!

1. Do you know, are left and right mouse buttons mappable in mouse mode?
2. Is it possible to assign two buttons to one toolbar button? Or to ignore state of shift key?

Game looks and performs mostly like Diablo. I expect same controls.
But when I shift-click mobs, to shoot them, while standing still on a spot, default attack shooting works, but additionally it set walking direction to that place. Since shift key is a modifier to hotkeys, when I press 1-9 keys to use hotbar actions, while shift pressed nothing happens. As soon as I release shift key to press an ability button 1-9 my character starts walking in the middle of mobs.

So I want to map right mouse click - walking, left - shooting. Or reverse, but different mouse buttons for different actions.
